Scale factor and perimeter are related because if the scale factor is 2, then the perimeter will be doubled. So whatever the scale factor is, that is how many times the perimeter will be enlarged.
The areas are related by the square of the scale factor.
There are: 70mm = 7cm
The scale factor is 1 to 150
That's in the right order.
There are 100cm in 1m, therefore 7cm x (1m)/(100cm) = .07m
2.54cm is an inch so, 1m 7cm = 107cm = 42.12 inchesSo, 3 feet 6.12 inches
It is 1 : 50.
The scale "4 cm = 1 m" is a factor of 1:25 (1/25th scale). 1m/.04m = 25
1007cm
to work out the scale we take the number of mm in 1m =1000 and then divide by the scale factor in this case 1:75 so 1000 divided by 75 = 13.333333333333333
1m 3 dm 7 cm 18 mm
7cm.
You increase the scale factor.
Tautologically!
The area scale factor is the square of the side length scale factor.
